1 States of Matter

2 What three things are made of matter? Solids, liquids, gases

3 What is mass? What is it measured in? A measure of the amount of matter in an object. Kilograms

4 What is volume? What is it measured in? A measure of how much space an object takes up. Milliliters (mL)

5 What can you use to measure the volume of a liquid? (3 Answers) Graduated cylinder, beaker, measuring cup

6 How do you measure the volume of a solid? Length X Width X Height Displacement

7 What two vocabulary words can be used to describe what matter is? Explain. Mass and Volume= Matter is anything that has mass and takes up space

8 What is weight? A force of gravity between Earth and an object

9 What measurement is used to measure weight? pounds

10 What is the same as pounds? One newton=0.22 pounds 4.45 newton=1 pound

11 What is the force of pull when dealing with weight? gravity

12 What does an objects weight depend on? Location in the universe

13 What stays the same as the astronauts go from Earth to the moon? What changes? Mass=SameWeight=Different

14 How does the astronauts weight on the Moon compare with the astronauts weight on Earth? Weigh less on the Moon

15 What are the two properties of matter? Mass and Volume

16 What is density? A measure of how tightly packed the matter is in an object.

17 How do you calculate density? Mass divided by Volume Ex: Mass 2g Volume 2mL Volume 2mL 2 divided by 2= 1 g per mL

18 What does high density mean? Also, draw a picture. Many particles are tightly packed in a given area.

19 What does low density mean? Also, draw a picture. A few particles fill the same amount of space.

20 What type of particles tend to be tightly packed together? solids

21 What type of particles tend to spread apart? Liquids or gases

22 List gas, solid, and liquid in order from most dense to the lease dense? Solid, liquid, gas

23 Why is water special? Solid water, ice, is less dense than liquid water. The particles in ice are more spread out than the particles in liquid water.

24 What determines an objects ability to sink or float? density

25 What word describes an objects ability to float? buoyancy

26 When will an object sink? When they are more dense than water.

27 What does conduct mean? Allow energy to flow through them easily

28 What does insulate mean? Do not allow energy to pass through

29 What type of items conduct energy? Metals

30 What should cooking pots and pans have on them and why? Wooden and ceramic handles so you do not get burnt

31 Why are metals good conductors? They conduct heat and electricity very well

32 What does the plastic on the wire help with? Works as an insulator around the wire

33 Name some items that are insulators.

34 What does magnetic mean? The push or pull on objects.

35 What two ends of a magnet attract? What two repel? Attract= Positive and Negative Repel= Positive and Positive Negative and Negative Negative and Negative

36 What are aerogels? Have very low density and great strength Used to insulate windows

37 What are the four properties of matter? DensityBuoyancyConductivityMagnetism

38 If a rock was taken from Earth to the Moon, how would its mass and weight be affected? Mass=Same Weight=Less on Moon

39 What are the three states of matter? Solids, liquids, gases

40 What can change substances into different states of matter? Adding or removing heat

41 Draw a picture of a solid, liquid, and gas?

42 When a solid has particles than begin moving faster and faster, what is going to happen to the solid? Eventually separate and become liquid

43 When a liquid has particles that being to move faster and faster, what is going to happen to the liquid? Become gas

44 What is melting point? solid to liquid

45 What is boiling point? Changes from a liquid to a gas

46 What does condenses mean? Turns from gas to a liquid

47 What does freeze mean? Liquid to a solid

48 What is another word for melting point? Freezing point

49 How is evaporation different from boiling? Evaporation=Gradual change from liquid to gas Boiling=Rapid change when heat is added

50 What are the properties of solids? 1.Retain (Keep) their shape 2.Same volume 3.Not a fluid

51 What are the properties of liquids? 1.Settle to the bottom of container 2.Definite volume 3.A fluid

52 What are the properties of gases? 1.No definite volume 2.Takes the shape of container 3.A fluid

53 What is expansion? To spread out when items get hotter

54 What is contraction? To shrink when items cool

55 How does a thermometer use expansion and contraction? The liquid in a thermometer expand when temperature rise, and contract when temperature decrease.

56 Give another example of expansion in every day life? You write down some examples! You write down some examples!

57 Give another example of contraction in every day life? You write down some examples! You write down some examples!
